Load testing with AWS

An instance of AWS with Openvidu initiated by the user is used as Sut and a parameterized test is executed whose values must be provided by the user (since they are AWS credentials). The test will start an Openvidu session with three users and check that they are all connected and receiving video and audio from the other users. Once checked, if everything is correct, it will start a second session with 3 other users.

It will be necessary to create the instance in CloudFormation with this file

  • Set OpenVidu Sut IP

Once created you must copy the Public DNS of the instance. In ElasTest, navigate to the Sut edit page and replace the value of Sut Ip field (Your OpenviduServer ip here) with the Public DNS.

  • Set AWS Private Key for OpenVidu

In th same page, replace the value of Private Key with your private key
